Babel-jest version 26.0.0 is a Jest plugin designed to seamlessly integrate Babel for code transformation within your testing environment. This latest release, dated May 4th, 2020, delivers key improvements over its predecessor, version 25.5.1, launched on April 29th, 2020.
A notable upgrade is the updated dependency on the chalk package, moving from version ^3.0.0 to ^4.0.0. This brings potential enhancements in terminal styling and color output during test runs. Core Jest dependencies have also been bumped, including @jest/types (from 25.5.0 to ^26.0.0) and @jest/transform (from 25.5.1 to ^26.0.0), aligning with the broader Jest ecosystem and benefiting from overall Jest improvements and bug fixes. Babel-preset-jest also received an update to version ^26.0.0.
While the devDependencies and peerDependencies remain consistent between the two versions, the updated dependencies suggest improvements in compatibility, stability, and potentially performance. Developers should be aware that updating might require corresponding adjustments in other Jest-related packages to ensure compatibility across the board. This update includes less files but the unpacked size suggests a more optimized packaging. Consider upgrading to benefit from the newest Jest features and potential improvements to Babel integration, while carefully checking for potential breaking changes introduced by the updated dependencies.
